In a parallelogram, opposite angles are congruent. However, the same thing cannot be said for the other.
You can label one pair of opposite angles with x and the other 9x.
You also know that each quadrilateral has interior angles that add up to 360 so you can create the equation of
9x+9x+x+x=360
which can be simplified into
20x=360
x=18
Now, you know the angle measures of one pair of opposite angles. to find the other you plug in 18 to our other equation and multiply 9 to get 162.
The angles of the parallelogram is 18,18, 162 and 162.
Note: you can check if this is right if all the angles add up to 360.
The horizontal component of the velocity = 800 cos 60 = 400 m/sec
400 = distance / time = 21000 / t
t = 21,000 / 400 = 52.5 seconds Answer
Answer:
Step-by-step explanation:
Question one
The slope is simply read. It is - 2
So far what you have is
y = mx + b
m = -2
y = - 2x + b
The point is a little different
(-1,1) means
x = - 1
y = 1
y = -2x + b
1 = -2(1) + b
1 = - 2 + b
1 + 2 = - 2 + 2 + b
3 = b
Complete line
y = -2x + 3
Problem 2
(0,-6 is where you should start. That's the y intercept. In the equation y = mx + b it gives you b immediately.
y = mx + b
-6 = 0m + b
b = - 6
The x intercept occurs when y = 0
0 = m(-2) - 6 Add 6 to both sides
6 = - 2m - 6 + 6
6 = -2m Divide by -2
6/-2 = m
m = - 3
Equation
y = -3x - 6
